As cell growth increases, the surface area to volume ratio does this.

Decreases

Surface area is important to cells for the exchange of these two things.

Waste and nutrients

What is DNA overload?

High demand on DNA info

By what process do prokaryotes divide?

Binary fission.

What is the reduced surface area to volume ratio of a cube with 4 cm sides?

3:2 98:64

This is the longest phase of the cell cycle

Interphase

This phase includes most of the cell’s growth and protein synthesis.

G1

Chromosomes replicate now.

S phase

Once a cell enters this phase, it will definitely divide.

S phase

Cytokinesis in a plant entails this.

A cell plate forms and it become a cell wall.

This phase of mitosis is often paired with cytokinesis

telephase

This phase of mitosis includes spindle fibers lengthening and shortening.

Anaphase Lengthening widens the cell Shortening pulls the chromatids apart

Name three things that occur in Prophase

1.Nuclear envelope dissolves 2. spindle forms 3. centrioles migrate to the poles

Describe exactly what results in mitosis

2 Identical Diploid cells

These proteins when injected into non-dividing cells cause mitotic spindles to form.

Cyclins

One set of chromosomes (1n) is known as this.

haploid

Crossing over occurs at this phase.

Prophase I

Meiosis is another word for this process.

Gametogenesis.

During this phase homologous pairs are separated

Anaphase I

Female gametogenesis results in this.

One viable egg and three polar bodies.

How are cancer cells described?

Lost the ability to regulate growth and division.

These two systems are key in metastasizing cancer cells.

Lymphatic and circulatory

These stem cells are totipotent.

Early embryonic stem cells.

What is the advantage of using adult stem cells from one’s own body for implantation?

No rejection.

Do you pay attention to the news? Cervical cancer (cancer of the cervix- an organ in the female reproductive tract) can actually be caused by THIS common virus.

HPV or Human Papiloma Virus
